A series of semiempirical molecular orbital calculations using the AM1 method were performed on the inclusion complexes of ␣and -cyclodextrin with benzoic acid and phenol in the ''head-first'' and ''tail-first'' positions. The AM1 results show that ␣-cyclodextrin complexes with both guest compounds

AM1 semiempirical molecular orbital calculations have been performed Ž . on the inclusion complexes of -cyclodextrin -CD with methylated benzoic acids in two orientations, the ''head-first'' and ''tail-first'' positions. In the former, the CO H 2 group points toward the primary hydroxyls of the CD
Molecular mechanics calculations were employed to study the inclusion of 2-methyl naphthoate in alpha- and beta-cyclodextrin in vacuo and in the presence of water as a solvent. The driving forces for complexation are dominated by nonbonded van der Waals host:guest interactions in both environments.
